Side-by-Side Comparison
| Spec | Garmin Instinct 3 Solar (45mm) | Suunto Race 2 (stainless steel) |
|---|---|---|
| Price | $399.99 | $499.00 |
| Release Year | 2025 | 2025 |
| Display | Monochrome 176x176 transflective MIP, always-on by design, no touchscreen — readable in direct sun and costs almost nothing to leave on | 1.5-in 466x466 AMOLED touchscreen with sapphire lens, optional always-on |
| Smartwatch Battery ( days) | 28 | 18 days with wrist HR on, 30 days in standby (Suunto). DC Rainmaker's review quotes up to 16 days — sources conflict. |
| Always-On Display Cost | There is no always-on penalty: MIP is always on. With 3 h/day at 50,000 lux the solar lens makes smartwatch mode effectively unlimited and stretches multiband GPS from 24 h to about 60 h. | Dual-band training time falls from 55 h to 50 h with the always-on display, per Wareable's testing notes — a smaller penalty than most AMOLED rivals |
| Battery, Single-Band GPS ( h) | Sources conflict: 40 h (the5krunner spec sheet, 45 mm, no solar) vs 50 h (garminrumors spec wiki, lower bound of its 45/50 mm range) | 65 |
| Battery, Multiband GPS ( h) | 24 | 55✓ |
| GNSS Bands | Multi-band dual-frequency L1+L5 (GPS, GLONASS, Galileo, BeiDou, QZSS) with SatIQ — DC Rainmaker confirms every Instinct 3 got multiband | Dual-band L1+L5. Suunto publishes 55 h in the dual-band Performance mode, 65 h single-band and 200 h in the power-saving Tour mode. |
| Onboard Maps | None. No offline maps and no route storage to speak of — DC Rainmaker called shipping a $400-plus outdoor watch without maps 'pretty hard to swallow'. | Free offline topographic maps for most of the world in 32 GB, downloaded over Wi-Fi with no cable and no charge. Maps are split into small regions (France alone is 27 sections) and there is no automatic rerouting — off-course you get compass guidance only. |
| Music Storage | None. No music storage, no streaming, no Wi-Fi — phone music control only. | None. No on-device music storage and no streaming; DC Rainmaker notes Suunto appears to be building toward it but it does not exist today. |
| Training Platform & Subscription | Garmin Connect is free and every core training metric — Training Readiness, Training Load, Training Status, HRV Status, Body Battery, recovery time — is Firstbeat-derived and free on the watch (Garmin bought Firstbeat in 2020). Connect+ is $6.99/mo or $69.99/yr and adds only AI wellness prompts, 3D maps, Trails+ routing, extra badges and nutrition logging — nothing a training plan depends on. | Suunto app is free with no subscription tier. Training analytics are Suunto's own; the watch also carries the Suunto Coach guidance layer at no cost. |
| External Sensor Support | ANT+ and Bluetooth chest straps, pods and power meters | Bluetooth sensors with multiple saved pairings — no ANT+ |
| Data Export | Full .FIT file access over USB/MTP plus free automatic sync to Strava, TrainingPeaks, Runalyze, intervals.icu and others through Garmin Connect. | Free .FIT export and automatic sync to Strava, TrainingPeaks, Komoot and 300+ partner services |
| Warranty | 12 months | 24 months |
| Colors | Black | All Black, Coral Orange |
Category Scores
GPS Accuracy
The Garmin Instinct 3 Solar (45mm) is marginally ahead, 8.6 to 8.2. A gap this small rarely decides a purchase on its own, though it counts if trace quality in cities and under tree cover — multiband L1+L5 hardware plus what independent testers measured in the real world. is your priority.
Battery Honesty
The Garmin Instinct 3 Solar (45mm) leads clearly here, 9.2 against 8.6 — a 0.6-point margin on how much of the headline battery claim survives the mode you would actually train in: all-systems plus multiband, always-on display, music playing. The number on the box is almost always the slowest, least accurate mode.. If that is what you are buying for, the Suunto Race 2 (stainless steel) does not close the gap elsewhere.
Training & Recovery
The Garmin Instinct 3 Solar (45mm) is marginally ahead, 7.8 to 7.4. A gap this small rarely decides a purchase on its own, though it counts if depth of load, readiness and recovery analysis, and how much of it is free rather than gated behind a subscription or an extra chest strap. is your priority.
Heart Rate
The Suunto Race 2 (stainless steel) is marginally ahead, 7.6 to 7.2. A gap this small rarely decides a purchase on its own, though it counts if optical wrist accuracy during intervals and burst efforts, and whether the watch pairs with ANT+ and/or Bluetooth chest straps as a fix. is your priority.
Display
The Suunto Race 2 (stainless steel) leads clearly here, 9.2 against 6.4 — a 2.8-point margin on brightness, resolution and daylight readability, weighing AMOLED sharpness against MIP's always-on-for-free behaviour.. If that is what you are buying for, the Garmin Instinct 3 Solar (45mm) does not close the gap elsewhere.
Build & Comfort
The Garmin Instinct 3 Solar (45mm) is marginally ahead, 8.2 to 8.0. A gap this small rarely decides a purchase on its own, though it counts if case materials, lens (sapphire vs glass), weight on the wrist and durability ratings. is your priority.
Value
The Suunto Race 2 (stainless steel) leads clearly here, 8.4 against 7.0 — a 1.4-point margin on what the watch delivers per dollar against everything else in the comparison at the moment of purchase.. If that is what you are buying for, the Garmin Instinct 3 Solar (45mm) does not close the gap elsewhere.

Pros & Cons
Garmin Instinct 3 Solar (45mm)
Pros
- +MIP plus solar is the one combination here where the headline battery figure is close to what you actually get
- +Multi-band L1+L5 GNSS at $399.99, in a 10 ATM, MIL-STD-810 tested case
- +Solar can push smartwatch mode to effectively unlimited and multiband GPS from 24 h to about 60 h
- +No always-on display penalty at all — the screen is transflective and permanently visible
Cons
- −No offline maps and no music storage, on a watch that costs as much as an Amazfit T-Rex 3 Pro that has both
- −Storage is the reason: sources conflict badly — the garminrumors wiki says 32 GB while DC Rainmaker and Tom's Guide report roughly 120-128 MB on Solar models, too small even to hold a firmware update alongside courses
- −Multiband drops runtime to 24 h without sun — a quarter of the 100 h Max Battery GPS headline
- −Older Elevate Gen 4 optical HR sensor, not the Gen 5 in cheaper Garmins
- −Monochrome 176x176 MIP screen looks a decade old next to every AMOLED rival, and there is no touchscreen
Suunto Race 2 (stainless steel)
Pros
- +55 h in the accurate dual-band mode — more than double what a Forerunner 570 manages at $50 more
- +Free worldwide offline maps in 32 GB, downloadable over Wi-Fi with no cable and no fee
- +1.5-in 466x466 AMOLED behind sapphire crystal at $499
- +DC Rainmaker rates the new optical HR sensor a 'massive improvement' and within the acceptable range for training
Cons
- −No music storage whatsoever — no MP3, no Spotify, nothing
- −Suunto's 18-day smartwatch figure and DC Rainmaker's 16-day figure do not agree
- −No automatic rerouting when you leave a course, and trails vanish from the map above roughly the 0.2-mile zoom level
- −Bluetooth only — no ANT+ sensors
- −DC Rainmaker measured a small GPS accuracy regression versus the original Race and Vertical
